WRIST-PIN BALANCE BLOCK.'

Application filed February 2, 1926. Serial No. 85,599.

' To all whom 717,653/ concern:

Be it known that I, CHARLES IV. lVnus'r, a citizen of thc United States, residing in Philadelphia, Pennsylvania, have invented new and uselul Improvements in VVrist-Pin Balance Blocks, of which the following is a speciiication. f

The object of my invention isrto provide a detachable counter-balance to be attached to the wristpin oi' a locomotive drivingside rods and box them separately, putting them, usually, in the tender of the locomotive. This method is objectionable, as the wheels are unbalanced and they strike the rail a hammer blow.

In some instances the locomotives have been sent to their destination with the rods in place and the main rods connected to the cross-head. This overcomes the hammer blow, but requires special attention and ad ditional lubricatioin'as the guides are liable to become heated and in some instances the guides are scored.

In theA accompanying drawing Fig. 1 is a side view of a locomotive driving-wheel with my detachable counter-balance in position;

Fig. 2 is an edge view of the wheel; and

Fig. 3 is an enlarged sectional view oi the detachable counter-balance mounted on the wrist-pin of a wheel. y

Referring to the drawing, the locomotive driving-wheel 1 is of the ordinary type, having a wrist-pin 2, and a counter-balance weight 3 made integral with the wheel and located opposite the wrist-pin.

A detachable counter-balance l is secured to the wrist-pin when the main rods and side rods are removed to allow the locomotive to be sent to its destinationon its own wheels, without steam, in order to counter-balance the wheel counter-balance 3, thus preventing the wheels striking a hammer blow on the rail. The detachable counter-balance 4 has a through opening vfor the reception of the part 5 of the wrist-pin and the opening is enlarged to tit over the flange Sand tapered portion T. The shoulder lot the counterbalance titsagainstthe flange 6 as shown in Fig. 3. y

On the end of the wrist-pin is a washer '8 which extends over the ycounter-balance 4:, and anut 9 on the threaded portion 10 of the wrist-pin holds the counter-balance firmly against the flange 6, as clearly shown in Fig.

GOy

3, y rIhe washer 8 is prevented from turning on the wrist-pin by a dowel pin l2.

The detachable n counter-balance can be readily applied to the wrist-pin when the rods are removed, and can be readily detached when desired. ter-balance will be of a weight which will balance the wheel.

I claim:

1. The combination ot' a locomotivedriving` wheel, having a wrist-pin and a counterbalance opposite the lwrist-pin; anda detachable counterfbalance mounted on the wrisbpin to balance the wheel when the rods are removed to allow the locomotive to travel on its own wheels, without its own motive power. V

2. The combination of a locomotive driving-wheel having a .vristpin and a counterbalance; a detachable counter-balance having a through opening for the wrist-pin; a

shoulder within the opening fitting againstr the flange of the pin and means including a vasher and nut for holding the detachable counter-balance on the pm.
